The problem addressed is the need for a secure, transparent, and efficient way to record and update digital asset transactions while maintaining data integrity and accessibility among authorized parties. The method involves processing a proposed transaction for a digital asset. When the transaction is committed, it creates a new active model of the digital asset, which is then recorded to a private shared ledger. The private shared ledger is accessible only to authorized participants, ensuring that transaction data remains secure while being verifiable by all authorized parties. The new active model represents the updated state of the digital asset after the transaction is executed, providing a clear and immutable record of changes. The system may include generating a transaction proposal, validating the proposal against predefined rules, and executing the transaction if validation is successful. The private shared ledger ensures that all authorized participants have a consistent view of the digital asset's state, reducing discrepancies and improving trust. This approach is particularly useful in scenarios where multiple parties need to collaborate on digital asset management while maintaining privacy and security.
11. The system of claim 10 wherein the proposed transaction includes per-ledger-entry authorizing data that identifies, for each of the one or more proposed ledger entries, one or more ledger-entry authorizing nodes that must authorize the respective proposed ledger entry.
This invention relates to distributed ledger systems, specifically addressing the challenge of ensuring secure and verifiable transaction authorization across multiple nodes in a decentralized network. The system enables a proposed transaction to include per-ledger-entry authorization data, which specifies the nodes responsible for authorizing each individual entry within the transaction.

The core technology involves an append-only ledger that is shared among multiple nodes in the network, where each node maintains a copy of the ledger. Transactions are cryptographically secured and committed to the ledger, making them immutable and verifiable by all participating nodes. The ledger operates as a public ledger, meaning all nodes have access to the same transaction records, ensuring transparency and consistency across the network. The cryptographic representation of each transaction ensures that any tampering with the data can be detected, as the ledger's integrity relies on cryptographic hashing and digital signatures. This design prevents unauthorized alterations while allowing all nodes to independently verify the validity of transactions. The system enhances trust in the network by eliminating single points of failure and ensuring that all participants agree on the state of the ledger. The invention is particularly useful in applications requiring high security, such as financial transactions, supply chain tracking, and digital identity management.
15. The system of claim 14, wherein the cryptographic representation of the committed transaction comprises a hash of the committed transaction.
A system for secure transaction processing involves generating a cryptographic representation of a committed transaction to ensure data integrity and authenticity. The system includes a transaction processing module that receives and validates transactions, a commitment module that generates a cryptographic representation of the committed transaction, and a storage module that stores the committed transaction and its cryptographic representation. The cryptographic representation is a hash of the committed transaction, providing a unique and tamper-evident fingerprint. This allows for verification of the transaction's integrity and ensures that any alteration to the transaction data would result in a different hash, making unauthorized modifications detectable. The system may also include a verification module that compares the stored hash with a newly computed hash of the transaction to confirm its authenticity. This approach enhances security in transaction processing by preventing unauthorized changes to transaction data while maintaining the ability to verify the original transaction details. The system is particularly useful in applications requiring high levels of data integrity, such as financial transactions, blockchain systems, or secure record-keeping.
16. The system of claim 10, wherein the proposed transaction, when committed, creates a new active model of the digital asset recorded to the private shared ledger.
A system for managing digital assets involves a private shared ledger that records transactions and maintains a distributed ledger across multiple nodes. The system addresses the need for secure, transparent, and tamper-proof tracking of digital asset ownership and transactions. The ledger ensures consistency and integrity by validating transactions through consensus mechanisms among the nodes. When a proposed transaction is committed, it creates a new active model of the digital asset, updating the ledger to reflect the latest state of the asset. This active model includes metadata such as ownership details, transaction history, and any associated conditions or restrictions. The system may also include mechanisms for verifying the authenticity of transactions, preventing double-spending, and ensuring that only authorized parties can modify the ledger. The private shared ledger operates in a permissioned environment, where participants must be authenticated and authorized to interact with the system. This approach enhances security and trust while maintaining the benefits of a distributed ledger, such as decentralization and immutability. The system is particularly useful in applications requiring high levels of security and transparency, such as financial transactions, supply chain management, and digital identity verification.
